Table 1: Concentration of Ce6 in tumor and normal tissues 4 h after i.v. injection in CBA mice at a dose of 10 mg/kg. Values are expressed in μg/g of tissue and given as means ± SD (n = 4). Lower case letter adenotes statistically significant difference (P<0.05) between marked and Ce6 groups, b – between marked and PDZ groups, c –between marked and all the other groups.
